To all whom it may concern:

Be it known" that we, ROY O. TILLFAMS and HARRY B. CoEN, citizens of the United States, residing at Columbus,'in the county of Franklin and State of Ohio, havelnvented certain new and useful Improvements in Water-Cooling Devices, of which the' follow-. ing is a specification. v U

Our invention relates to water cool ng devices and resides primarily in the provislon' of a water cooling device which combines the action of a pump with the action of cool1ng the water and thereby renders possible the elimination of all pumping means or other devices for forcing the water to the cooling device under normal conditions.

Our invention is primarily applicable to the cooling of the jacket water of internal combustion engines and particularly of en-- gines upon automobiles, although the scope of our invention is not limited to this particular art.

The primary essential of our improvement resides in the fact that the water to be cooled is drawn in positively by the actlon of the cooling device. This'cooling device preferably ta (es the form of arotating element which acts by its rotation to suck in the water and todischarge it in the path of air. This rotating element is preferably formed to simultaneously draw in a certain,

quantity of air for mixing and direct contact with the indrawn water. Also, the indrawn water is preferably discharged into contact with the indrawn air in disin tegrated form and is preferably caused to be broken up into flying globules presenting a gradually increased superficial area to be acted upon by the cooling air. By the utilization of our improvement, we are enabled to do away with the usual pump attached to water cooling devices for maintaining circulation and in the application of our device to motor vehicles, we are enabled to dispense with not only this pump, but the fan which is utilized in the present day type of cooling apparatus for automobiles. Our improve- .ment in application to the normal automobile, produces a saving of approximately ninety per cent. of the cost of construction, for the reason that it takes the place of the radiator, the pumping device and the fan.

- The preferred embodiment of our invention is shown in the accompanyin drawings, in which similar characters 0 reference designate corresponding parts, and in which:

Figure 1 is a side elevation of an auto-' mobile engine with our cooling device applied thereto and shown as positively driven from the driving shaft of the automobile, Fig. 2 is a side elevation of our improved cooling device detached, Fig. 3 is an end view of the structure shown in Fig. 2, Fig. 4 is a section taken on line 4-4 of Fig. 3, and, Fig. 5 is a section taken on line 55 of Fig.4.

Inasmuch as the cooling device proper is the essential element of our invention, it will be well to describe this cooling device initially, therefore attention is directed to Figs. 2, 3, 4 and 5 wherein there is shown-a casing 1 preferably of drum-like form having a water outlet 2 at a lower point in one side thereof which is in turn provided with an outwardly leading air passage 3. This drumlike casing may be formed with a cylindrical body 4 and annular side pieces 5 and 6 havmg their centers cut away as at 7 and formed with inwardly bent edges 8 and 9 forming annular troughs to catch and conduct the dripping water from the inner surfaces of the side pieces so as to preclude the downward drip of the water from the side Walls across the central cut-out portion. The cylindrical body portion 4 desirably incloses a plurality of cylindrical screens 10 and 11 which are preferably spaced apart by spacing elements 12 and which in turn surrounds a somewhat smaller rotary element comprised of spaced rings 13 and 14 held apart by and carrying fan blades 15 preferably concaved in the direction of travel of thesaid rotary element and preferably arranged at determinate inthe said Figs. 2, 3, 4 and 5, but which may.

be similar in form to that shown in Fig. 1. This hollow shaft 20 is mounted in bearing sleeves 23 and 24carried by bearin brackets 25 and 26 and the said shaft is he (1 against lateral movementin these bearing sleeves by means of collars 27 and 28 whlch may be looked upon the said shaft by set screws 29.

The shaft is rotated by any suitable means and we have shown a bevel gear 30 as a medium of rotation.

In operation of this device, the rotation of the shaft 20 while in communication with a column of Water, will operate by a centrifugal and siphoning action of the rotating hollow spokes to continually draw in water and discharge it through apertures 31 in the transverse conduit elements mounted upon the ends of the spokes. Simultaneously the fan blades 15 will serveto draw in air through the cut-outcentral portions of the side pieces 5 and 6 and will cause a constant current of air passing through the casing. The water will be discharged from the transverse conduit elements by the combination of a suction produced by the travel the said transverse pieces through the air, a. siphoning action and centrifugal force. In its discharge from these'tran'sverse conduitelements, the water is partially disintegrated and flies through the air until it reaches either the fan blades 15 or the reticulate elements 10 and 11. The major portion of the discharged waterwill strike upon the fan blades 15 and will be broken up into flying globules of water in direct contact with the indrawn air at thestrongest point of its draft. .There will necessarily result a rapid andefiicient cooling action, due largely to the fact that the water is broken up and evenly distributed around the path of draft and is permitted to pass through the at mosphere and in direct contact therewith from the moment it leaves the transverse hicle comprises a water jacket 32 having circulating pipes 33 leading therefrom and connected as at 34 by a water tight bearing to the open end of the hollow shaft 20. The delivery spout 2 of the casing is further shown as connected by piping 35 with a tank 36 from which'leads a manifold pipe element 37 into the jacket 32. This manifold pipe element has its lower end extending directly into the tank 36 and may be joined therewith by a threaded sleeve 38 and a union 39. At this point of union, we desirably mount a check valve 40 under the control of a spring 41. The purpose of this check valve is to maintain a head of water in the jackets and circulating pipes of the engine. The hollow shaft 20 with its. bevel gear 30 is preferably driven by a coacting bevel pinion 42, shaft 43, bevel pinion 44 and bevel gear 45 mounted upon the driving shaft 46 of the engine, this driving shaft being of normal form and being shown in connection with a cranking means 47 which may be of any suitable form.

In the operation ofthis apparatus the Water is drawn from the water jacket surrounding the cylinders through pipes 33 and into the hollow shaft, and is discharged radially through the spokes of the rotating element into the casing, where it is cooled and passes from thence through delivery spout 2 to the tank 36, from which water is supplied to the water jackets of the cylinders through pipe 37. The continual suction maintained by the rotating'element,

causes the water to continue its circulation through the pipes 37, water jackets, pipes 33, casing 1 and tank 36, while the check valve in pipe 37 prevents the back flow from the water jackets to the tank and also sup- 35 ports a sufiicient volume of water, in said pipe when the apparatus is at rest, to start up the circulation simultaneously with the commencement of rotation of the hollow shaft 20.
